The main technical specifications of external compression
Oxygen booster with oxygen compressor.
•Feed air compression, pre-cooling and purification systems
Feed air from atmosphere is removed dust and mechanical impurity
through air filter then enters into Air Compressor. Compressed air
with pressure of 0.7Mpa(G) is sent into Air Pre-cooling System to
be cooled down to 5~8°C.
Cooled air enters into Molecular Sieve Purification System for
adsorption in where moistures, carbon dioxide, acetylene and other
hydrocarbons impurities are removed. There are two alternative
working vertical adsorbers. When one adsorber works another will be
Purified air with temperature of 10~16°Cfrom Molecular Sieve
Purification System is sent into Main Heat-exchanger in where the
purified air is cooled down by reflux cryogenic flow to saturation
then goes into rectification column.
The liquid air we got in the bottom of column is sent to
condensor-vaporizer on the top of column as condensate liquid after
throttling. The oxygen riched liquid air in the condenser
-vaporizer is sent to main heat exchanger and rewarm up tp -152°C
and then goes into turbo expander for expansion. The oxygen riched
air return back to the cold end of heat exchanger after expansion,
in there oxygen riched air are rewarmed to normal atmospheric
temperature and then goes out of cold box. They will be used as
regeneration gas and other superlus will be vent.
The product nitrogen drawn out from the top of column to heat
exchanger for rewarming and then send out of cold box to nitrogen
we supplied to many countries (Russia, Kazakhstan, Tajikistan,
India, Bangladesh, Thailand, Philippines, North Korea, Mongolia,
Equatorial Guinea, Botswana, Zambia, Angola, Tanzania) .
High reliability. Low pressure process. Low power consumption.
Short time delivery. Good service.
